MP-4000 motor protection
protection of three-phase AC motors. The
MP-4000 motor relay may be applied to any size
motor at any voltage level. It is most commonly
used on large, medium voltage three-phase induction motors. It has also been widely used on
important low voltage (480V) motor applications
and synchronous motors.
The MP-4000 motor relay monitors three-phase
and ground currents and three-phase voltages.
It provides motor overload, stall, short circuit,
phase unbalance, single phasing over/undervoltage, underpower, power factor, and ground fault
motor protection.
It can also be used to provide protection for a load
jam or loss of load condition.
Product description
The MP-4000 motor relay provides start control
logic to protect the motor against excessive starts
or starting the motor before it has had sufficient
time to cool down. The MP-4000 motor relay
may be applied to either across-the-line starters
or reduced-voltage starters. On reduced-voltage
starters, the MP-4000 relay can control the switch
from reduced voltage to full voltage based on time
and/or motor transition. The MP-4000 can protect
the starter against failure to transition to full voltage through contact feedback and an incomplete
sequence function.

The MP-4000 motor relay is generally used on
a motor starter or a breaker used for a motor
load. The MP-4000 motor relay provides the
intelligence to protect and control the motor
against abnormal operating conditions. It monitors
the currents from either a 5A or a 1A secondary
of a CT circuit. Ground current may be obtained
from either a ground CT or from the residual
connection of the phase CTs. It provides a Form C
contact output for controlling the starter contacts
or breaker operation.

The MP-4000 is available in either a fixed mount or quick release
drawout case. Both mountings use the same panel cutout.
The Universal RTD module (URTD) is required when the motor is
equipped with RTDs that you wish to monitor and use for protection. The URTD can be mounted near the motor to reduce RTD
wiring and costs.
The MP-4000 motor protection is designed to operate from 120 Vac
or 240 Vac auxiliary control power. The MP-4000 motor relay can be
used with DC control power with the addition of the IQDCPS. The
IQDCPS is an inverter from DC to AC.
